i2c/for-5.2
Mainly some pca954x work, i.e. removal of unused platform data support
and added support for sysfs interface for manipulating/examining the
idle state. And then a mechanical cocci-style patch.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL);
This code was detected with the help of Coccinelle.

If the parent has an atomic callback, we need to translate it the same
way as the non-atomic callback.

Due to a typo, the wrong parent device was assigned to the newly created
demuxing adapter device. It got connected to the demuxing platform
device but not to the selected parent I2C adapter device. Fix it to get
a proper parent-child relationship of the demuxed busses.

The demux device is only a logical device with no children. So, no
RuntimePM is needed, let's disable the sysfs interface for it.

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Some drivers like i2c-gpio do not have dedicated pinctrl states. They
broke when error checking for pinctrl was added. Detect them now, and in
their case, simply skip over pinctrl configuration.

We can't use a static property for all the changesets, so we now create
dynamic ones for each changeset.

We also need to revert the dynamic OF change, so we get a consistent
state again. Otherwise, we might have two devices enabled e.g. after
pinctrl setup fails.

sysfs attributes should use the same format for reads and writes,
rather than pretty-printing on read.
* Make the "cur_master" attribute read back as just the name of the
master
* Expose the list of all masters as a read-only "available_masters"
attribute, using space separators as in similar attributes of other
devices
Also, spell out "cur_master" in full as "current_master".

This driver allows an I2C bus to switch between multiple masters. This
is not hot-switching because connected I2C slaves will be
re-instantiated. It is meant to select the best I2C core at runtime once
the task is known. Example: Prefer i2c-gpio over another I2C core
because of HW errata affecting your use case.
